RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 11/833,817 filed on Aug. 3, 2007, which in turn is a continuation of U.S. Provisional Patent Application No. 60/835,395, filed on Aug. 3, 2006, and U.S. Provisional Application No. 60/848,970, filed on Oct. 3, 2006, each of which is incorporated by reference herein in their entirety.

FIELD OF THE INVENTION

The present invention relates to systems and methods for the placement and powering of video screens for the purpose of distributing real-time information. Embodiments of the present invention relate to the relaying of advertisement information, operational information, and other information by utilizing a satellite or other wireless communication devices and/or and local informational supplying devices.

BACKGROUND OF THE INVENTION

Companies rely on advertising to generate millions of dollars in business from independent consumers each year. Companies often employ a variety of advertising techniques, such as electronic (television, radio and the internet) as well as still images (billboards or print media) to disseminate information about their products to potential consumers. In order to be successful, companies must place their information in locations where it will be viewed by the largest number of potential consumers. In order to be successful in the advertising business, companies must develop strategies to reach the maximum number of potential customers with each type of advertisement.

Countless companies place their advertisements on electronic media to be viewed, perceived, or noticed by customers. An example is radio advertisements that air throughout the day on commercial radio stations. This strategy may not be effective as many people switch to a different radio station when commercials begin to air. In addition, as more Americans begin to utilize internet and satellite radio, the power of radio advertisement will further decline.

Many companies also utilize television advertisements to increase awareness about their products. This strategy, while effective, can present a cost prohibitive barrier to many smaller businesses. Companies must not only pay for the airtime on the network, but must also pay to create the commercial. The companies must also investigate the best time to air their commercial so it will reach the maximum number of viewers. Network airtime during very popular shows can be very expensive for a short time slot. In addition, with the advent of technologies such as TiVo® (TiVo, Alviso, Calif.) more people pre-record television shows and subsequently skip the commercials.

Recently, companies have begun to advertise their products on the World Wide Web. Advertisers can purchase space on popular websites to display “banner ads”. Consumers can click on the ad to be directed to the company's website or a retailer of the product. Many advertisers also employ “pop-up” ads that open a new browser window when an individual visits a particular website. Some consumers have found these advertisements to be annoying or intrusive and have employed pop-up blockers to block the advertisements or have switched to internet service providers that do not use advertisements.

In addition to the various electronic advertising strategies, companies also employ still or print advertisements. Companies may employ a variety of media for placement of their advertisements. Companies will often place their advertisements in newspapers or magazines. However, fewer consumers are obtaining their news from print sources as more and more people turn to electronic news sources. Potential consumers may not see the advertisements.

As individuals have become more mobile, companies have turned to the use of large print advertisements displayed in retail areas or along heavily traveled highways. Retailers will often advertise their products within a shopping area, such as a mall, to attract customers to their stores. However, many businesses rely on advertising at locations remote from their place of business. Often these retailers will place advertisements along major highways in an attempt to induce customers to visit their location off of the highway. Technology has advanced within the last decade to allow for rotating billboards. These displays allow for more than one company to place their advertisement on a single billboard, and the image rotates at a pre-determined time interval. Some companies have also begun to employ electronic billboards that display various ads on LED, LCD, or other types of display screens. Rotating and electronic billboards, while more effective than single image billboards, cannot be changed in real time with changes in the area.

In addition to billboards or other signage in retail areas, companies may also use their own delivery trucks to advertise their products while they are in transit. Still other retailers may place their information on independently owned vehicles simply for advertising purposes. Customers can view the vehicles while traveling on the highway, and this viewing can increase brand recognition. Currently, vehicles can be painted with the advertisement or fitted with a billboard advertisement on the side of the vehicle. While many consumers may view the vehicle while traveling on the roadway, the signage is difficult to change if a different message is desired.

Thus a new way of delivering advertising content, as well as other informational content, to consumers and the general public is needed.

DETAILED DESCRIPTION

By way of example, in order to provide an understanding of the invention, embodiments of the present invention are described with reference to a tractor trailer vehicle and a stationary billboard. It should be appreciated by the remainder of the disclosure herein, that the present invention is not limited to the embodiments described below but may comprise other embodiments for use with other vehicles, including, but not limited to, trucks, automobiles, motorcycles, boats, planes, barges, balloons, or similar vehicles designed for travel over land, air or water, as well as all-types of trailers in tow, or other stationary screens.

Advertising is a dynamic business that must change in response to changes in the social climate or pressures from the marketplace. Companies must continually update their advertisements to fit with the current trends or desires of consumers. Current methods require a significant time and monetary investment by the company to alter their advertisement. Thus, a faster, easier method to change advertisements is desirable.

As society becomes more technologically advanced, consumers have come to rely on real-time and current information. The use of cell phones and mobile devices capable of internet access has exploded in the past decade as Americans desire to be in touch at all times. A technology that allows for real-time dissemination of information along highways would present an advance to consumers who wish to remain connected and to receive real-time information. Vehicles, screens, or billboards equipped with a display according to embodiments of the present invention that display information in real-time could provide the desired information to consumers.

Some advertising display systems may exist that provide for updateable information display. However, the conventional systems do not address the safety of individuals and drivers that view the display of advertisement. The conventional systems may create a moving safety hazard because a fellow driver's attention may be distracted by reviewing the advertisement. It is desirable for a system of displaying advertisements and other information in real-time while taking into consideration the safety concerns of fellow drivers. Embodiments of the present invention may provide greater safety protection for the drivers and consumers. Embodiments of the present invention can enhance the safety of consumers that are reviewing the advertisements or other displayed information.

In one embodiment, the present invention provides a system comprising a vehicle; a video display attached to the vehicle wherein the video display can be positioned in a housing; a wireless data transfer device wherein the wireless data transfer device comprises a wireless receiver, the wireless receiver being capable of receiving data transmissions; an operational sensor device wherein the operational sensor device can detect changes in the operation of the vehicle; a controller wherein the controller receives signals from at least one source, the at least one source comprising the wireless data transfer device or the operational sensor device, and further wherein the controller can transmit signals to the video display; and a plurality of power sources wherein at least one of the power sources comprises a power source that is independent of the power supply of the vehicle. In some embodiments, the system may comprise a video display that can be attached to a supporting frame. The video display and supporting frame can be repositioned to provide an unobstructed entry and exit into the vehicle. In a further embodiment, a vehicle may contain a retractable static advertisement. When the static advertisement is in the retracted position, at least one projector may project an image upon the blank screen. The retractor device and at least one projector can have a sensor to trigger the operation of the retractor and projector.

In an embodiment of the present invention, a video display of varying thickness may be affixed onto vehicles, such as tractor-trailer trucks as shown in FIGS. 1-13. As found in FIGS. 1-13, the video display can be attached by using different techniques and in different positions. The display may be of different sizes depending on the information to be displayed and the type and size of location of placement on a vehicle, screen, or billboard. The thickness of the video display may vary. In an embodiment where the video display is affixed to the vehicle, it is preferable that the size and thickness of the display not impede safe operation of the vehicle. A representative, but not to be considered limited, thickness of a video display for mounting on a vehicle is about three inches. The possible types of video displays include, but are not limited to, LCDs, LEDs, plasma screens, projection screens, CRT screens, optical fiber screens, and other display screens. The video display may be powered by any number of different power sources, including, but not limited to solar, wind, or a rechargeable power source.

In some embodiments, a system of the present invention comprises a wireless data transfer device for receiving information transmitted by any of a plurality of transmitters, such as Bluetooth® technology (Bluetooth SIG, Inc., Bellevue, Wash.), satellites, cellular telephones, a wireless network, Wi-Fi, internet, or intranet. Information received by the wireless data transfer device may be communicated to the display through the controller for displaying. The vehicle may also comprise a position locating device, such as a GPS system, to determine the location of the vehicle. The information can be sent over air waves to the wireless transfer device.

In another embodiment, information to be displayed is stored remotely from the system, for example on a computer system and/or hard disk. Information from the computer system and/or hard disk may be communicated to the system for displaying. In some embodiments, the information may be communicated over air waves. The hard disk/computer system may be updated to provide new information for system and the video display. In a further embodiment, a wireless receiver can be used to update the hard disk with new information.

In some embodiments, an operational sensor device can be used to detect changes in the vehicle operation indicators and change the information being displayed. An example, not to be considered limiting, of a vehicle operation indicator is the application of the brakes of a vehicle. In this non-limiting example, when the brakes are applied, the operational sensor device detects a stimulus (for example, the application of the brakes), transmits a signal to the controller, the controller processes the signal, and the controller transmits a signal to the video display to display some defined message that indicates the brakes are being applied. Other examples of vehicle operation indicators can include application of the accelerator, blinkers, direction indicator lamps, change of bearing, and other like indicators.

A video display of the present invention may vary in size depending on the size of the vehicle. Video displays must be of minimal width to be mounted on the side or back of a vehicle. Due to their considerable thickness and weight, video display screens may need to be reduced in width. The width of the video display may not impair the vision of the driver. In some embodiments, the width can be less than about three inches. In other embodiments, the width of the video display can allow the clearance of the roll-up back door. In some embodiments, video displays may be composed of a series of panels. In some embodiments the panel construction can be utilized so as to not impair the functioning of the roll-up back door of the truck.

Typical LCD screens are eight inches in width, potentially too large and heavy to be mounted on the side of a vehicle. In order to accommodate mounting on a vehicle, an LCD screen may be broken down into its component parts with only the screen being mounted on the side or back of the vehicle. It can be desirable to mount the other components of a display screen on other parts of the vehicle to prevent a weight imbalance created by mounting a heavy screen and component parts on the side or back of a vehicle.

In some embodiments, the video display may be attached to the rear of the truck and positioned on a supporting frame. In some embodiments, the supporting frame can comprise horizontal members and vertical members. The supporting frame can provide a structure in which the video display can be mounted.

In some embodiments, the frame can be attached to the rear of the vehicle. The attachment device can comprise of a hinge or other like device. In one embodiment, at least one hinge can be attached to the vehicle and the supporting frame. The hinge can allow the supporting frame and the video display to be swung open around the central axis of the hinge to a position that does not interfere with the loading and unloading of a vehicle. In some embodiments, the hinge can be swung open around the central axis of the hinge to about 90° from its closed position. In some embodiments, the hinge can be swung open around the central axis of the hinge to about 110° from its closed position.

In some embodiments, the hinge may be oriented vertically so that the supporting frame swings open to an orientation where the display screen of the video display remains substantially perpendicular to the ground. In other embodiments, the hinge may be oriented horizontally so that the supporting frame swings open where the display screen of the video display transitions to be substantially parallel to the ground. In some embodiments, the hinges oriented horizontally may be positioned on a top horizontal member. In other embodiments, the hinges oriented horizontally may be positioned on the top section of vertical members.

In some embodiments, when the hinge is oriented horizontally, it allows the video display to be substantially parallel to the ground's open position, the video display may be repositioned on the top of the vehicle. In this embodiment, the hinge provides about a 90° angle of rotation. When the supporting frame and video display are in the open position, the supporting frame may be slid into a second frame comprising track bars.

In some embodiments, the video display can be displayed on the top of the vehicle. In some embodiments, the video display can be attached to a rotating device. The rotating device is capable of rotating the video display over a range of angles. In some embodiments, the range of rotation can be 360°. In some embodiments, the range of rotation can be about 180°. In other embodiments, the range of rotation can be about 135°. In other embodiments, the range of rotation can be about 90°. In some embodiments the video display can be rotated automatically or according to a pre-determined routine.

In other embodiments, the video display may be displayed on top of the vehicle in a stationary position. The video display may be flipped up so that the display screen can be visible from ground level. In some embodiments, a hinge or like device can be used to reposition the video display so that it may be viewed from ground level. In some embodiments, track bars into which a video display can be stored may be connected to the top of a vehicle via a hinge or other like device. By reorienting the track bars by using the hinge, the video display can be displayed to individuals at the ground level. In yet other embodiment the track bars may be positioned on a rotating device that rotates the entire track bar structure. By rotating the entire track bar structure, the video display can be visible from a plurality of positions on the ground level.

One exemplary embodiment of the present invention can be found in FIG. 1. FIG. 1 illustrates an embodiment of a system of the present invention. The vehicle 10 has the video display 12 attached to the side 20 of the vehicle's trailer. The video display 12 can be connected to a control box 14. Within the control box 14, among other devices, a controller, a wireless data transfer device, a power supply, and/or a position locating device can be located. The connection between the video display 12 and the control box 14 can be provided by wires, cables, and other connectors known to one of ordinary skill in the art. In some embodiments, the connecting wires may be mounted along the side of the vehicle, along the top of the vehicle, or along the back of the vehicle. In other embodiments, the connecting wires may be incorporated into the side 20. In some embodiments, wind turbines 18 and/or solar panels 16 may be used as a mechanism to generate power for the system. Although, in the embodiment as shown, the control box is positioned on the top 22 of the trailer, it should be understood that other placement configurations are possible including, but not limited to, positions such as behind the cab of a tractor trailer, inside a trailer, or any other suitable locations.

FIG. 2 illustrates a top view of an embodiment of a vehicle with the video display 12 mounted to the side 20 of the trailer. In the embodiment illustrated in FIG. 2, the control box 14 is positioned on top 22 of the trailer. The plurality of wind turbines 18 and the solar panel 16 can be utilized to generate power for the controller and video display to operate.

In one embodiment as seen in FIG. 3, a video display 28 can be attached to roll-up door 26 positioned on the back 24 of the trailer. The video display 28 can comprise of a plurality of panels. In FIG. 4, for illustrative purposes only and not to be considered limiting, the video display 28 is comprised of four panels: 29, 30, 31, and 32. The video display panels 29, 30, 31, and 32 correspond to the paneled construction of the roll-up door 26. When the segmented, paneled roll-up door is lifted into the open position, the paneled construction of the video display 28 allows the display to mirror the operation of the roll-up door, as illustrated in FIG. 5. FIG. 5 is a side view of a trailer as found in FIG. 3 with a portion of the trailer cut away. The video display panels 29, 30, 31, and 32 can roll-up in the same manner of operation as the roll-up door. The paneled, segmented construction of both the video display 28 and the rollup door 26 allow the transition from a closed position (a substantially flat position) to a curved position (during the act of opening and closing as seen in FIG. 5) to an open position (a substantially flat position).

Some video displays may be quite sensitive to jarring movements, such as those experienced while driving. Without protection, some video display screens may quickly break due to the potential bumping and jarring as a vehicle travels on a roadway. In some embodiments, in order to prevent damage to a video display, a screen may be positioned in a housing comprising a protective case. The housing may reduce the level of jarring or shocking by the vibrations of the vehicle traveling on a roadway. In some embodiments, the housing can comprise shock absorbent material where the shock absorbent material decreases the forces acting upon the video display during the operation of the vehicle. In one embodiment, a video display can be mounted such that it “floats” within a protective case and is not jarred by road movement. Enclosing a video display in a protective case can also provide protection of the video display from scratches, vandalism, or the weather. In some embodiments, the protective case can be made from a study plastic that is transparent, resistant to scratches, and can be easily cleaned.

Plastics that can be used include but are not limited to polymers such as acrylics, various laminates, polypropylenes, polyethylenes, methacrylic polymers, polycarbonates, polystyrenes, cyclic olefinic polymers, fluoropolymers, polyesters, polyarylates, polysulfides, polysulfones, other sulfur containing polymers, polymethylpentene polymers, polyolefins polymerized with a metallocene catalyst, polyolefins, allylester polymers, polyamideimid polymers, fullerene polymers, propylene-ethylene copolymers, other copolymers, and other transparent polymers or combinations thereof.

The video display and other components can be powered by one or more of several power sources, such as solar power, rechargeable batteries, or wind power. Where the video display is affixed to the vehicle, a video display may be powered by rechargeable batteries that are recharged by the engine of the vehicle, by solar power, or wind power. It is desirable to provide an alternative power source for a video display so that the screen does not diminish either the fuel or battery of the vehicle on which it is mounted. In an embodiment, the power can be collected by a power generating source, such as solar panels or wind turbines and then stored in rechargeable batteries or a generator for use by a video display, controller, and other devices. When affixed to a vehicle, an alternate source power arrangement is also desirable so that the video display may continue to operate even when the vehicle is stopped or not turned on. In such embodiments, a video display may continue to display information even after the vehicle has stopped. For example, a video display may continue to display images or news after the vehicle has stopped to refuel or stopped for the driver to rest. A power source for the system may be mounted on the top of a vehicle, along the front side of a trailer of a tractor-trailer truck, or other suitable positions.

In order to display advertisements or information, a video display may be connected to a wireless data transfer device via a controller to receive data transmissions for display on the screen. Information received by the controller may be relayed to the video display and displayed on the side or back of a vehicle. In a further embodiment, a wireless receiver device may be positioned on the top of a vehicle to receive transmissions from a plurality of transmission sources. Such transmission sources may include Bluetooth® technology, wireless transmitters, satellite transmitters, Wi-Fi, internet, or intranet. Data signals may be transmitted from such devices to a transmitter located on a vehicle and further transmitted from a control box to a video display screen for display.

In some embodiments a vehicle may be equipped with a position locator device, such as a GPS device, to transmit the position or location of a vehicle to a wireless or satellite receiving device. The positional information of a vehicle can then be used to direct information that is specific for, relevant to, and/or desired for the location of a vehicle.

In other embodiments, advertising information regarding specific products can be transmitted to a wireless receiver for display on a video display screen. Such advertising information may be targeted or changed depending on the location of the vehicle, screen, or billboard. Because the information is transmitted wirelessly, it can be updated in real-time or changed at pre-determined intervals of time or distance.

In an embodiment, the information relayed to a wireless receiver may include important news or traffic information that is relevant to the position of a vehicle. Such information may include traffic reports, accident reports, or traffic delays. Other information may include breaking news stories or public service announcements, such as AMBER alerts.

In a further embodiment, the information on the display screen affixed to a vehicle may change due to the transmission of a signal from an operational sensor device connected to vehicle. The operational sensor device can detect signals or information from a plurality of vehicle operation indicators, such as, but not to be considered limiting, application of the brakes, the application of the accelerator, blinkers, direction-indicator lamps, change of bearing, and other like indicators. For example, but not to be considered limiting, when the vehicle is braking, the operational sensor device would transmit a signal to the controller to interrupt the current video display information with a second message. In one embodiment, upon the application of the brakes, an interrupting message notifies on-lookers or motorists that the brakes of the vehicle have been applied. The message may be a fixed or a flashing video display. The controller can receive the information or signal and process the information or signal to determine the information or message to display on the video display. In some embodiments, when the vehicle is fully stopped, the controller can send a signal to the video display to display the product advertisement instead of the interrupting message.

FIGS. 6a and 6b illustrate an exemplary embodiment where the video display has changed as a result of the application of the brakes. FIG. 6a depicts a vehicle that does not have the brakes applied. FIG. 6b depicts a vehicle of FIG. 6a after the brakes have been applied as found in video display 24. In some embodiments, the video display 12 may also display the interrupting message resulting from the operational sensor device.

The operational sensor device can provide valuable information to enhance the safety of the onlookers. For example, the intermittent brake signal notifies drivers of the slowing of a vehicle. In some embodiments, the time between the application of the brakes and the displaying of the message on the back of the vehicle is less than two microseconds. While an on-looker may be focused on the content being displayed on the video display, the onlooker will not be able to dismiss or ignore an interrupting message notifying him or her of an operation change of the vehicle. For example, and not to be considered limiting, an onlooker would be unable to dismiss the message “BRAKING . . . Please slow down” that appears in a large sized type and in some embodiments, flashing. The operational sensor device may transmit a signal via a circuit device used within the art.

In another embodiment, a display screen with a retractable static advertisement or informational display may be affixed to the vehicle. The display may be retracted upon the triggering of a sensor by a specified stimulus. After detecting the specified stimulus, the sensor triggers a retractor device to retract the static advertisement. In one embodiment, the sensor can be a light sensor. When the static display image is in the retracted position, a blank screen is present. The blank screen may then be used as a surface to display a video image of different advertisements or information. The different advertisements or information may be displayed by at least one projector, LCD screen, or like screen. The at least one projector, which may be positioned either at the side or rear, can be triggered by a sensor to project the advertisement or information on the blank screen.

FIG. 7 illustrates one embodiment of the present invention. The representative screen 36 is shown as a projector 38 and 40. Other types of screens may also be utilized, including LED, LCD plasma, rear projection, optical fibers, and the like. The screen may vary depending on the size of the vehicle, and/or the screen may comprise individual panels arranged to produce a large display. The display can be powered by one or more of several power sources, such as solar power 16 or wind power 18. The lumination of the at least one projector may be from the side or rear of the screen. The screen is capable of displaying multiple messages in multiple forms. The view indicates the presence of a retractable static advertisement 36. After the triggering of a light sensor, a retractor device 34 retracts the static advertisement 36 leaving a blank screen which is positioned behind a static advertisement 36. When the static advertisement 36 is in the retracted position, a sensor can trigger the at least one projector or LCD to display an image onto the blank screen.

FIGS. 8-9 depict an embodiment of the present invention where the video display can be attached to the back of a vehicle. Referring to FIG. 8, the video display 72 can be attached a supporting frame comprising horizontal members 78 and vertical member 79. On one end, the horizontal members 78 can be connected to the back 24 of the vehicle by a hinge 74. On the opposite end of the horizontal members 78, attachment devices 76 can be positioned. The attachment devices 76 can provide a mechanism to secure the video display 72 and the horizontal members 78 to the back 24 of the vehicle. In some embodiments, the horizontal member 78 can be connected by a vertical member 79. The vertical support 79 can provide a structure to connect the horizontal members 78. The vertical support 79 can prevent and/or reduce the bending or bowing of the horizontal members 78. Other configurations of the supporting frame can be utilized within the scope of the present invention.

When the attachment devices 79 are engaged, the video display 72 is in the closed position, as found in FIG. 8. When the attachment devices 79 are not engaged, the video display can be swung open into the open position, as found in FIG. 9. In the embodiments depicted in FIGS. 8-9, the hinges are oriented vertically. In some embodiments, the hinges 74 allow the video display to be opened to about a 90° angle from the closed position. In other embodiments, the hinges 74 allow the video display to be opened to about a 110° angle from the closed position. The orientation of the display screen of the video display 72 is substantially perpendicular to the ground.

When the video display 72 is in the open position, the vehicle may be loaded and/or unloaded. The open position allows the unobstructed entry and exit into the vehicle. When the video display 72 is in the closed position, the video display can be available to display a plurality of information.

In some embodiments, an existing vehicle may be retrofitted according to embodiments of the present invention. The video display may be attached to a supporting frame comprising horizontal members and at least one vertical member. The supporting frame may be affixed to the vehicle by hinges and/or attachment devices. The hinges may be positioned to not interfere with the operation of the vehicle's rear door.
